A passive tire breaker that can be deployed temporarily

Abstract

The invention discloses a passive tire breaker capable of being temporarily arranged. The passive tire breaker comprises a shell, a tire breaking needle, a rotating shaft, a key, a torsion spring and a shaft sleeve; the head end of the tire breaking needle is a triangular-pyramid-shaped blade, the two side edges of the blade are provided with grooves, the tail end of the tire breaking needle is provided with a tail end pad block and a tail end limiting block, and the middle portion of the tire breaking needle is provided with a through hole structure matched with a rotating shaft; the right side of the shell is provided with a shaft hole structure matched with the rotating shaft, the upper surface of the shell is provided with a cutter outlet groove extending to a right-side slope of the shell, the two sides of the cutter outlet groove in the upper surface of the shell are provided with boss structures matched with the grooves of the head end of the tire breaking needle, a force unloading structure of the shell is cooperated with the tail end pad block, a limiting structure of the shell is cooperated with the tail end limiting block, the rotating shaft is installed in a shaft hole structure of the shell through the shaft sleeve, the initial positions of the rotating shaft and the shell are limited through the key, the torsion spring is embedded in the rotating shaft, one end of the torsion spring is connected with the shaft hole structure of the shell, and the other end of the torsion spring is connected with the tire breaking needle. The passive tire breaker can still be used when totally isolated from a power supply.

Description

technical field [0001] The invention relates to security equipment, in particular to a passive tire breaker which can be deployed temporarily. Background technique [0002] The tire breaker is a security device commonly used by the police, anti-terrorism and anti-riot personnel to maintain social order and crack down on the law. This is not efficient and can easily cause traffic paralysis. [0003] Existing tire breakers are basically divided into two types, one is a fixed tire breaker, which is mainly placed in important places such as highway toll stations, prisons, and government buildings. Although the lifting and landing of the tire breaking needle can be controlled by remote control, the tire breaking effect can be effectively realized, but it needs to be installed on the ground in advance and the installation is relatively difficult. , it is inconvenient for the police to carry it with them, it cannot deal with emergencies, and it cannot be used in passive places. ...

AI Technical Summary

Problems solved by technology

Although the tire breaker has a high degree of automation, it needs to be installed on the ground in advance, and it is only suitable for fixed places. It is inconvenient to move, and the flexibility is not enough, so it is not convenient for the police to carry it around.

It cannot be used in passive places and there is no force unloading device. When the car hits, it will cause damage to the structure and it is not easy to maintain

The other is a portable tire breaker. Although it is easy to carry and has strong flexibility, it needs to be manually moved and used. The process is complicated, it cannot be automated, and it cannot selectively block vehicles. great hindrance

For example, the application number 201610400809.2 discloses a portable tire breaker for stopping vehicles. At least one module base is installed in the aluminum alloy composite base, and tire breaking nails and guards are installed on the module base. The rolling positioning end cover is installed, and the wall thickness from the top wall of the shield to the wall thickness of the shield side wall is normally distributed, and the shield is buckled with the shield buckle of the module base through the shield buckle folded inward. Install the card slot and buckle connection, and there are symmetrical oval holes on the rolling positioning end cover. The tire breaker has high strength and is stable in landing and gripping the ground. However, the use process of the tire breaker is complicated and needs to be moved manually. Selective blocking of vehicles is not efficient and the weight is heavy and the law enforcement process is quite cumbersome
